Climate Change in India

Affects of Climate Change in India

Unpredictable Monsoons

Climate change has made monsoons unpredictable in India. As a result, rain-fed wheat cultivation in India will suffer in a big way. Total cereal production will go down. The crop yield per hectare will be hit badly, causing food insecurity and loss of livelihood.

Climate change washes off Hudhud in India

On the 12th of October 2014, the city of Visakhapatanam along with its neighbouring coastal villages in the district witnessed a climate catastrophe of an unimaginable scale.Cyclone Hudhud with wind speeds close to 220kmph ransacked the entire landscape of the city leaving people homeless and stranded!

Affects on Metro cities

Kolkata and Mumbai are vulnerable to extreme river floods, intense tropical cyclones, rising sea levels and high temperatures.
Droughts are expected to be more frequent in some areas, especially in north-western India, Jharkhand, Orissa and Chhattisgarh. Crop yields are expected to fall significantly because of extreme heat by the 2040s.

Glaciers Melt

At 2.5°C warming, melting glaciers and the loss of snow cover over the Himalayas are expected to threaten the stability and reliability of northern India’s primarily glacier-fed rivers, particularly the Indus and the Brahmaputra. The Ganges will be less dependent on melt water due to high annual rainfall downstream during the monsoon season.

The Indus and Brahmaputra are expected to see increased flows in spring when the snows melt, with flows reducing subsequently in late spring and summer.

Alterations in the flows of the Indus, Ganges, and Brahmaputra rivers could significantly impact irrigation, affecting the amount of food that can be produced in their basins as well as the livelihoods of millions of people

Health Impact

Climate change is expected to have major health impacts in India- increasing malnutrition and related health disorders such as child stunting - with the poor likely to be affected most severely. Child stunting is projected to increase by 35% by 2050 compared to a scenario without climate change.

Malaria and other vector-borne diseases, along with and diarrheal infections which are a major cause of child mortality, are likely to spread into areas where colder temperatures had previously limited transmission.

Heat waves are likely to result in a very substantial rise in mortality and death, and injuries from extreme weather events are likely to increase.

Water Shortage

An increase in variability of monsoon rainfall is expected to increase water shortages in some areas.Studies have found that the threat to water security is very high over central India, along the mountain ranges of the Western Ghats, and in India’s northeastern states.
